Serological study of bovine viral diarrhoea virus infection of cattle in Ahwaz

ABSTRACT

In order to investigate the prevalence of infection with bovine viral diarrhoea virus [BVDV] of cattle in Ahvaz, blood samples were collected from jugular vein of 572 cattle [521 female, 51 male] from industrial and nonindustrial farms. Sera were stored at -20?C while waiting for analysis. The sera were tested by ELISA, using a commercial ELISA kit for detection of specific antibody to bovine viral diarrhoea virus [BVDV]. The results were analyzed by chi- square test. 163 [28.5%] Out of the sera samples were positive. The results showed the seropositivities of 29.55%, 17.64%, 75% and 23.34% in female, male and animals in industrial and non- industrial farms, respectively.
